The area of a triangle is found by multiplying half of the measure of its base by its height. The area of the following right triangle is 18 square centimeters.
A. Write and solve an equation to find the value of h. Include all of your work in your answer.
B. In two or more complete sentences, verify your answer using mental math.
Answer:
AREA OF TRAINGLE =18
WE NO THE AREA OF 1/2 BH
B=6
PLUGGING IN THE VALUES
18 1/2 6 (H+1)
6=H+1
H=5
Suppose a tank leaks toxic chemicals. The area affected is a circle centered on the tank. When the spill is first noticed, the circle has a radius of 60 meters. A response team arrives 70 minutes later, by which time the affected area has grown to a circle with a radius of 80 meters.
Required:
How rapidly was the radius of the spill changing between the time the spill was noticed and the arrival of the response team?
Answer:
0.5 ft per min
Step-by-step explanation:
in 80 minutes the radius expanded by 40%
we can set up a proportion of percent change over minutes:
.4/80 = r/1
cross-multiply to get:
80r = .4
r = .005 or 1/2 of a foot per minute.
Hope It Helps :)
The radius of the spill changing between the time of the spill was noticed and the arrival of the response team is 2/7.
What is an equation?Mathematical expressions with two algebraic symbols on either side of the equal (=) sign are called equations.
This relationship is illustrated by the left and right expressions being equal to one another. The left-hand side equals the right-hand side is a basic, straightforward equation.
As per the given information in the question,
Let the radian of the spill at time t be μ(t).
Since, radian increases at a constant rate, we have,
dμ/dt = k
r(t) = kt + c
At t = 0, r = 60 m
60 = k(0) + c
c = 60
At, t = 70, r(70) = 80 m
80 = k(70) + 60
20 = 70k
k = 20/70
k = 2/7
Then, r(t) = 2/7t + 60 and the rate of change of radian of the spill is 2/7 per min.

Answer:
Step-by-step explanation:
To find the area of a rectangle in square inches simply multiply your measurements for length and width to determine the area of your square or rectangular area in square inches. For example, let's say that, for a rectangular area, you measure a length of 4 inches and a width of 3 inches. In this case, the area within your rectangle is 4 × 3 = 12 square inches.

A marketing researcher must determine how many telephone numbers she needs to order from a sample provider to complete a survey of ATM users. The goal is to complete 400 interviews with ATM users. From past experience, she estimates that 70 percent of the phone numbers provided will be working phone numbers. The estimated incidence rate (percentage of people contacted who are ATM users) is 45 percent. Finally, she estimates from previous surveys that 37 percent of the people contacted will agree to complete the survey. How many telephone numbers should she order to complete the 400 interviews
Answer:
the required number of telephone orders to complete the 400 interviews is 3433
Step-by-step explanation:
Given the data in the question;
Let us represent the telephone numbers the researcher orders to complete the 400 interviews with Y.
Thus, The working phone numbers = 70% × Y
Now, number of ATM users = 45% × The working ph0ne numbers
⇒ 45% × ( 70% × Y )
number of ATM users = 0.45 × 0.70 × Y = 0.315Y
Thus; Number of people contacted that agrees to complete the survey will be;
⇒ 37% × number of ATM users
⇒ 0.37 × 0.315Y = 0.11655Y
so, since the researcher needs at least 400 interviews
Hence;
0.11655Y ≥ 400
Y ≥ 400 / 0.11655
Y ≥ 3432.0034 ≈ 3433
Therefore, the required number of telephone orders to complete the 400 interviews is 3433

Plugging in our values,
[tex]area = ( \frac{2 + 8}{2} ) \times 3 = ( \frac{10}{2} ) \times 3 = 5 \times 3 = 15 {cm}^{2} [/tex]

The notation "m^2" is a shorthand way of saying "square meters".
Chances are you'll simply type in the number and leave out the units, as that's already taken care of.
==========================================================
Work Shown:
area = base*height
area = 8*3
area = 24 square meters
---------
Explanation:
We simply multiply the base 8 and height 3 and that's our answer. It's not a trick question even if it might seem like it.
The side that's 7 meters long is never used. The base and height are always perpendicular to one another, which means that they form a right angle (aka 90 degree angle).
The area formula of a parallelogram and rectangle are the same. We can think of a non-rectangular parallelogram as a slanted rectangle in a sense. Imagine you had stacks of blocks to form a rectangle. Now imagine nudging that stack slightly to one side. The blocks themselves don't change, so the area of one wall doesn't change. All that's changed is the shape.
